A pair of complementary filters are used in many applications, for example, in low-sensitivity filter structures and filter banks. 파틱클 필터 (Particle Filter) Part 05. This webpage briefly explains why such a filter is necessary, how it works, and then offers some alternative filters that you might consider. For example, from the frequency domain perspective, if the first output implements a lowpass filter, the second output implements the power complementary highpass filter. Since it is possible to obtain the FIR filter coefficients by applying an impulse response, following the logic of phase cancellation, it would be possible to obtain the power complementary filter coefficients by subtracting the output of the prototype filter from a copy . The algorithm could be used as an initialization step in an orientation filter or some of the techniques presented in the Lowpass Filter Orientation Using Quaternion SLERP could be used to smooth the motion.

For real signals, the power complementary output is computed by subtracting the output of the second branch from the first. In addition, in many applications, the need arises to split the input signal into two or more frequency bands. The complementary filter is one of the widely adopted techniques whose performance is highly dependent on the appropriate selection of its gain parameters. But I think my understanding on the principal behind it is still unclear. Complementary Filter (CF) Often, there are cases where you have two different measurement sources for estimating one variable and the noise properties of the two measurements are such that one source gives good information only in low frequency region while the other is good only in high frequency region.
